"Ken Jautz, the executive in charge of CNN, said in an internal memo that the schedule change was made to improve political coverage this year. Mr. King will be the network's top campaign correspondent for the remainder of the presidential election cycle. He had a similar role during the 2008 presidential election cycle.

"'This is John's seventh presidential campaign, fourth with CNN, and making him available across our programming lineup allows us to better tap his skills and experience, especially on the ground reporting in major battleground states and among critical voting blocs,' said Mr. Jautz, referring to Mr. King."
